Characterization of a novel 1,3-bis(p-iminobenzoic acid)indane Langmuir-Blodgett film for organic vapor sensing.

In the present paper we report about the Langmuir-Blodgett thin film characterization and organic vapor sensing properties of a novel 1,3-bis(p-iminobenzoic acid)indane (IBI) containing polar carboxylic acid groups. LB film properties of IBI material is characterized by UV-visible spectroscopy, atomic force microscopy, and quartz crystal microbalance. Our results show that high-quality and uniform LB films can be prepared with the transfer ratio of over 0.95. Organic vapor sensing properties are studied using quartz crystal microbalance measurement system. IBI film is found to be significantly more sensitive to benzene and the response of LB sample is fast, large, and reversible. The sensitivity of detection of toluene, ethyl alcohol, and isopropyl alcohol is much smaller than that of benzene. This newly synthesized IBI is a suitable molecule for the fabrication of an LB film and can be regarded as a promising sensing material in the development of a room temperature gas sensor for benzene vapor applications.

A rare case of HSV-2 encephalitis.

Herpes simplex viruses (HSV), and especially HSV-1, are the most common cause of acute, sporadic viral encephalitis. HSV-2 is an uncommon cause of encephalitis. We report a rare case of HSV-2 encephalitis that was free of genital lesions. In terms of the patient's case history, she had a Cesarean section four months before, herpes labialis 30 days before, varicella zoster 20 days before. We discuss the possibility that postpartum stress may be one of the factors in this case.

Human fascioliasis.

Fasciola hepatica, a zoonotic liver fluke, can also cause disease in humans. Common symptoms are epigastric pain, upper abdominal pain and malaise. Fever and arthralgia are common in acute fascioliasis. Eosinophilia is the predominant laboratory finding, especially in patients with the acute form of the disease. Diagnosis and treatment is not easy, as physicians rarely encounter this disease, and effective drugs are not available in many countries. Human fascioliasis may be underestimated. Patients with eosinophilia and abdominal pain should be evaluated for F. hepatica infestation by parasitological, radiological and serological tests.

Cervical pregnancy: can age and parity be predisposing factors?

A fifty-year old woman, gravida 17, para 17, presented with profuse vaginal bleeding following curettage in another hospital. At emergency laparotomy total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed because of intractable hemorrhage. Histopathologic examination revealed endocervical placentation and adenomyosis uteri. The case is presented due to its rarity and possible predisposing factors are discussed.
